The anti-corruption watchdog had on Thursday registered an FIR against Naidu and nine others, including his son Katta Jagadish Naidu, a city corporator, over alleged irregularities in Karnataka Industrial Area Development

Board land purchase and securing compensation for land acquired by it.

The FIR said Naidu allegedly had a role in the allotment of 385 acres to ITASKA Software, a firm set up by one of his aides to establish a SEZ while he was industries minister in 2007.

The Lokayukta had arrested his son Jagadish a few months ago for allegedly trying to influence a witness.

He

later obtained bail from the high court.

Naidu

is the third minister to quit this year after H Halappa, who resigned after rape charges were levelled against him, and R Ramachandra Gowda, following allegations of recruit scams.
